*fixed bug where recent files did not construct a proper path+filename when invoking it from a command line (at startup)

made a simple animation (toggle visibility) when tracking an error associated with a toplevel canvas. Use broken box font colors for error link in console.

Added methods to change coordinate data for shapes: data, points, x, y, height, width, cx, cy, r, x1, y1, x2, y2, and rx, ry for ellipse

fixed rx and ry methods, update scrollbars when scalar is displaced, and update bbox on changes to visibility and stroke-width

*added comments with future TODOs

*added usability feature where if invalid object is activated, when leaving focus, try to recreate it
*added experimental disabling of scrollable array windows (currently disabled as this should be fixed once we begin using a more up-to-date GUI)
*fixed obscure bug where editor was being improperly destroyed in a subpatch when it shouldn't be
*cosmetic fixes

*improved draw sprite so that it works within a group

*patch to add [group] data structure and supporting fixes (work in progress with lingering bug of being unable to display data structure arrays properly, see tiger.pd demo patch in data structures)

*partial backport of a fix to allow subpatches to be renamed with no arguments without losing their inner content (see g_text setto call). Thanks to Jonathan Wilkes for the bug report.

*improved comment resize bar (made it into a dashed box)
*improved invalid object outline (box) into a dashed box and made such boxes solid when being edited to distinguish them from comments.
